Does/will it support primary/replica cluster for AWS ElastiCache?

[debuggeryang]

Hey,

I know it may be not a good place to ask this question but I can't find anywhere else to ask it.

I see the package https://github.com/colinmollenhour/Cm_Cache_Backend_Redis support the ElastiCache (cluster disabled mode), and that is for Magento2 cache. However, the session only has Redis Sentinel relevant configurations. Why?

Thanks

I've not dealt with ElastiCache before. If you provide a PR I'd be happy to review and merge it though. Thanks!
